Finding social media startups

I run a social media news blog(http://fastgush.com) where I also cover social media startups. I have been facing the difficulty of finding social media startups. Until now, I have looked at HN for new startups, but lately there have been very few of them in social media space. So, If you are building/built/know an app or a site related to social media, please contact me at contact@fastgush.com. Would love to hear from you..
